` s 11 Claims.

The invention is a manually 4controlled punch for perforating sheets of paper andits objectresides in providing a simplied punch construction having spaced brackets to slidably guide normally raised and resiliently controlled perforating or cutting tools adapted to be downwardly displaced .by :spaced inverted yoke shaped actuator vmembers pivotally mounted on spaced channeled shaped members carried by the brackets, the yoke vshaped members being str-adrdled by the channel shaped members .and -concomitantly operated by a. unitary handle for Idownwardly displacing :the .cutting tools. The invention has as another object the provisionof spaced rods disposed widthwise of the yoke shaped' actuator members and spaced from the fulcrum means Vpivotally sustaining the actuator members for depressing the resilient controlled cutting tools upon manual displacement of the handle. Other important features and structural and functional aspects of the invention will appear from the following detailed specication considered in the light Yof the faccompanying drawings wherein:

Fig. 1 is a perspective view of the perforating device according to my invention. p

Fig. 2 is a plan view of Fig. 1. v

Fig. 3 is a longitudinal sectional Aview on th line 3 3 of Fig. 2. v

Fig. 4 is a transversessectional view on the line 4-4 of Fig. 3 and Fig..5 is a View similar to Fig. 4, .illustrating vthe handle depressed for operating the cutting tools.

The cutting tools or punches T are slidably `and vertically guided in alined openings I- and Il of the spaced `upper and lower arms I2 and I3 of sheet metal brackets B and in openings I4 of the U shaped saddles S having their lower walls I 4 xed by rivets l5 to the arms `I2 ofthe brackets whereby wings IB of the saddles S closely straddle the upper arms I?. and extend appreciably above the latter and characterize means for xedly retaining fulcrum pins I1 on vwhich the spaced and depending ears .I8 of the spaced actuator members A closely straddled by wings l are pivotally mounted.

The `tool actuator @members A each xedly carries a cylindrical tool .driving 4.pin y.or abutment brace 20 extending `widthwise across the chan* nel thereof 'and each actuator member A is provided with aligned front and rear .lugs 2l and 22 integrally extending from the upper wall 23 for fixedly retaining spaced arms .24 'of the handle Ahl which is preferably formed of 4a relatively rugged perforated rod orheavy wire having -tapered portions A25 merging into the anterior arcuate portion or loop 26 iixedly retained and snapped 'into the annular groove 2-'1 of the disc shaped thrust receiving head or knob 28.

As previously stated, pivoted tool actuatorsA characterize channeled shaped members with the upwardly extending lugs 21| and 22 thereof projecting from the front and :rear ends of walls 23 and normal to the spaced ears I8 depending from the sides of the inclined walls 23 common to lugs 2l and 22 and depending ears t8. SaddlesS may also be said to be channeledshaped members.

Lower arms I 3'of the brackets B are spaced ,from the die plates D but are secured .thereto -by rivets l29 passing through offset lips y3l] and the paper supporting base plate P. 'I'he upper arms I2 eachembody an inclined .rear leg 3l :having an offset lip 32 fixed by rivet `33 to the die plates on platform P. However lips 3U are integrally merged tothe lower arms I3 bythe inclined portions 34. Brackets B may be `said to be channel shaped sheet metal stanchions for slidably guiding the cutting tools T. `Hence die plates D and the brackets dene gaps Gtopermit insertion of one or more sheets of paper PP positioned rst under and then perforated by `the punches or cutting tools T and insertion of the paper is limited by the fixed stop 34' disposed .medially of the base.

The tool steel punches 'I' each include a restricted neck 35 in which is rlxedly secured the annulus vor flange 36 ycharacterizing Va stop to limit upward displacement of the .cutting tools each of which is surrounded by `a helicoidal spring 31 which serves to automatically elevate punches T from the perforations -38 in the die plates and from the latter upon removal of hand pressure on knob 28. During such operation the upper parts of the cutting tools `drive the fixed rods or braces 20 causing tool actuators A to be bodily rocked or tilted rearwardly about the fixed fulcrum pins I1, and hence handle H is pivoted or raised rearwardly and normally is held in such raised or tilted position, being limited in its rearward displacement when rear corners 40 of the .spaced depending ears I8 of the actuators A strike the upper Walls "I2 of 'thebrackets Preparatory to punching, one or more sheets of paper PP are .first vinserted into gaps G until they strike the fixed projection stop 3d. Thereafter handle I-I is manually depressed. Consequently actuators A are rocked or pivoted for Wardly. Hence the xed rods 2D cause the tools T to be shifted downwardly `and against the resistance of .the springs 31 which `become cornpressed due to the displacement Aof xed ring shaped flanges 31 carried by the tools. The tools pass through the sheets of paper and into the die plates and the severed portions 4D of the sheets of paper fall into wells 4I and onto a closure 42 rotatably mounted on screw 43 threaded into the'platform or paper supporting base P. The screw is so adjusted that the upper surface of the rotatable closure 42 normally frictionally bears against surface 45 of the circular recess 46 and thus the closure may be held in a desired closed or open position and extends diametrically of the recess to close wells 4I or may be conveniently moved by finger pressure to be free olf thewells to permit the latterl to be emptied.

The base P and knob 28 are of a suitable wood or plastic while the remaining parts of Athe perforating device are of metal, although the cuttingtools are of tool steel and it should be observed that on downward displacement of the wired handle, front and spaced corners 41 of actuators A cooperate with the upper horizontal arms of the brackets or stanchions B to limit such downward displacement. If desired a graduated gage bar 48 overhanging the platform has one end secured in the notch 49 thereof by a isuitable set screw 50. The spaced. die plates D however are initially positioned in the spaced elongated recesses I disposed longitudinally of the base-P and characterize means for initially positioning the die plates relative to the base and are of such depth to arrange the upper faces 52 of the die plates substantially flush with the upper surface 53 of the base, the forward walls of the recesses or notches 5| being uninterrupt- D ed and curved to position and limit the displace- Various changes may be made in details of construction and arrangement of parts without departing from the spirit of the invention or sacrificing any of the advantages therein.
